Plasma display panel (PDP)

Abstract

A Plasma Display Panel (PDP) includes: a first substrate including a plurality pairs of sustain electrodes, each of which includes an X electrode and a Y electrode separated from each other by a discharge gap, formed on a lower side thereof, and a first dielectric layer covering the pairs of sustain electrodes; a second substrate facing the first substrate and including address electrodes formed on an upper side thereof to cross the pairs of sustain electrodes, and a second dielectric layer covering the address electrodes; and a barrier rib including first barrier ribs formed on the second dielectric layer to interpose at least one address electrode therebetween, and second barrier ribs crossing the first barrier ribs to define discharge cells, in which a phosphor layer is formed. Each X electrode and each Y electrode respectively include bus electrodes, and transparent electrodes having protrusions, which are spaced apart from the second barrier ribs and corresponding to the discharge cells, and extension units extending from the protrusions and connected to the bus electrodes.

Description

CLAIM OF PRIORITY [0001] This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application for PLASMA DISPLAY PANEL earlier filed in the Korean Intellectual Property Office on 18 Feb. 2004 and there duly assigned Serial No. 2004-10671. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a Plasma Display Panel (PDP), and more particularly, to a PDP having an improved discharge efficiency resulting from the prevention of mis-discharges and the ensuring of an address voltage margin. [0004] 2. Description of the Related Art [0005] In general, in a PDP, a glow discharge is generated by supplying a predetermined voltage to electrodes, the electrodes having a gas filled sealed space therebetween. A phosphor layer formed in a predetermined pattern is then excited by ultraviolet rays generated by the glow discharge to display an image. [0006] PDPs can be classified as D...

AI Technical Summary

Benefits of technology

[0016] The present invention provides a PDP having an improved sustain electrode structure for preventing mis-discharges from occurring and for ensuring an address voltage margin, thereby improving the PDP discharge efficiency.

Problems solved by technology

In addition, unnecessary wall charges are accumulated, and it is not easy to control the wall charges.

Especially, in the discharge operation for initializing the wall charges to turn the discharge cell off after generating a discharge in the discharge cell, it is not easy to control the wall charges, and accordingly, a possibility of a mis-discharge occurring increases.
